I hope this helps someone else, because it stumped me for two days. The ttyACMO would disappear right after reset and I could not upload any sketch. I found the fix here https://arduino.stackexchange.com/quest ... erial-port I give that guy all the credit for this and this topic should be pinned, because it took forever to fix it.
